#22631 — Removing ' ' from strings ??

Hi:

    I'm probably having a senior moment, but with IE8 as a test bed, I 
cannot seem to replace ' ' with an ordinary space character.

    e.g.,

    Let's say my input text string is:

        var mytext = "  " + "Hello" + " " + "World" + 
" "

    Using IE8:

        var newtext = mytext.replace(" "," ") ;

    The above statement*works* in Chrome (i.e., it replaces ' ' with an 
'ordinary' space character

    But, in IE8 , these ' ' sequences are *not* replaced -- just 
ignored ??

I need a 'kick-in-the-butt' please -- perhaps a real regex string that would 
work in all cases ?

Thank you.

-Mel Smith

No, only the first one.

IE11 does the same as chrome, are you sure about IE8?

Better always use regex with replace(),
and use the global switch if necessary:

var newtext = mytext.replace(/&nbsp;/g,' ') ;

On my IE8 VM, the code works as expected.

Ben & Evertjan:

    I'll go back to my 'real' code and take another look. I probably (as 
usual) did something wrong --- *but* Chrome worked perfectly ??

Thanks,

Hi All:

    My IE8 still won't change the nbsp; coding to spaces altho Chrome does 
so.

    Below is my actual latest test code

    and here is the definition of my alltrim() function

function alltrim(str) {
   return str.replace(/^\s+|\s+$/g,"") ;
}

Thanks

-Mel Smith


********* latest test code *************
option = el.options[nindex] ; // text string with multiple 'nbsp;' in it
textstr = option.text ;
textstr = textstr.replace(/nbsp;/g," ") ; // change nbsp; into space 
globally

// get the clubname first
npos1 = textstr.search("Tees") ;
clubname = textstr.substring(0,npos1) ;
alert("a. Code at start= " + clubname.charCodeAt(0)+"  Code at end= 
"+clubname.charCodeAt(clubname.length-1)) ;
clubname = alltrim(clubname) ;   // trim spaces off of the ends of the 
clubname
alert("b. Code at start= " + clubname.charCodeAt(0)+"  Code at end= 
"+clubname.charCodeAt(clubname.length-1)) ;
// in both alerts above the chars at the start and end are Unicode 160 
(unbreakable space) for IE8

alert("clubname=**"+clubname+"**  Len = "+clubname.length) ;

"nbsp;" is not the same as "&nbsp;".

Hi:

    The corrected real code is below.

    Unfortunately, the result id the same:   is replaced by " " for 
Chrome but *not* for IE8


********************
option = el.options[nindex] ; // text string with multiple 'nbsp;' in it
textstr = option.text ;
textstr = textstr.replace(/ /g," ") ; // change ' ' into space 
globally

// get the clubname first
npos1 = textstr.search("Tees") ;
clubname = textstr.substring(0,npos1) ;
alert("a. Code at start= " + clubname.charCodeAt(0)+"  Code at end= 
"+clubname.charCodeAt(clubname.length-1)) ;
clubname = alltrim(clubname) ;   // trim spaces off of the ends of the 
clubname
alert("b. Code at start= " + clubname.charCodeAt(0)+"  Code at end= 
"+clubname.charCodeAt(clubname.length-1)) ;
// in both alerts above the chars at the start and end are Unicode 160 
(unbreakable space) in IE8

alert("clubname=**"+clubname+"**  Len = "+clubname.length) ;

Is that script code you have inline inside of an HTML document? Or why 
do you use an HTML entity reference?
Have you tried
   textstr.replace(/\u00A0/g, ' ')
?

    Yes, it is in a javascript function in an html doc that is getting the 
text string from a option of a <select> tag -- but maybe I don't undestand 
what you're asking ??

    No, but I'll give it a try.

Thanks Martin.

Then the replace won't work.  /&nbsp;/ does not match U+00A0 (160
decimal), it matches an ampersand followed by an 'n' etc.  You can
replace both by writing:

  textstr.replace(/&nbsp;|\u00a0/g," ")

Hi Ben:

    In just tried your /\u00A0/g  code and it works perfectly.

Thanks !

option.text may not be the same as option.innerHTML, especially if the 
html contains entity codes. I suspect the issue is that the html entity 
codes have been translated into some other encoding scheme (ie other than 
html entity encoding) in the text string that you're getting back as the 
value of option.text.

Hi Denis:

    I ave simple text (with the inclusion of    codes, and MArtin's 
solution resolves everything nicely. IE* and Chrome react exactly the same.

    I tried 'innerHTML' for a few minutes, and came up with the long string 
of chars interspersed with  

    So, back to Martin's solution.

Thanks to all !
